BALL-COCK.

SPECIFICATION forming part ef Letters Patent Ne. 617,59*?, dated January' 1o, ieee.

v Application filed September 7, 1897. Serial No. 650,720. (No model.) u I T LZZ whom, it may concern,.-

Be it known that I, TIMOTHY J. MCHUGH, of Cambridge, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Ball- Cocks, of which the following is a specification.

This invention has relation to ball-cocks for supplying water to iiushing-tanks and other like purposes; and it consists of a device of the character mentioned possessing certain features of construction and arrangement which are clearly illustrated upon the drawings and are now to be described and claimed, in which the valve is seated against the pressure of the water in such way as to prevent pounding.

Reference is to be had to the accompanying drawings, and to the letters and figures marked thereon, forming a part of this specication, the same letters and figures designating the same parts or features, as the case may be, Wherever they occur.

Of the drawings, Figure 1 shows in longit-udinal section a ball-cock embodying my invention. Fig. 2 represents a plan view of the same. Fig. 3 represents a section on the line 3 8 of Fig. l. Fig. 4t shows the valve as moved away from its seat to permit the free iiow of water. Fig. 5 shows in detail the valve detached.

Referring to the drawings, the valve-casing a is formed with the cylindrical portion ct' threaded, as at ft2, and with the enlarged por-` tion as, having the downwardly-extending discharge-spout a4. In the enlarged cylindrical portion a3 is placed a pipe b, formed on its end into a valve-seat b'. A supplypipe b2 is formed with a conical end b5, and the threaded end a2 of the casing is flared, so that the end of the internal pipe b is clamped against the casing bythe collar b, which has a flange b4 to bear against a shoulder b5 on the end thereof.

The valve-casing is formed with laterallyprojecting wings a5, through which screws a6 are passed to secure it to the side'A of a tank. It is also provided with longitudinally-extending arms a8, each having a slot which extends downward, as at 2, and forward, asat 3, and

c c ofthe float-lever c', the said pivots being located in the central the casing.

The spherical portion ctg of the casing is provided with a downwardly-extending partition a9, which is perforated to receive a sliding cylindrical valve d, having secured in its front end by a screw Cla disk washer cl2, adapted to be pressed against the valveseat b'. The valve projects through an aperture in the end of the casing 'and is provided in its projecting end with a transverse slot d3 to receive a trundle or roller c2 on a pin c3, extending between the two arms c4 c4 of the float-lever 'c'. The said float-lever is provided with a transverse aperture c5 to receive a bent rod e, to the free end of which is secured the iioat or ball e. The rod ve is provided With a short arm 4 and a long arm 5 and is heldin place in the lever by a setscrew c, so that by loosening the screw and removing the rod the fioat e' may be placed upon the arm 5 and the arm 4 secured in the lever to obtain a greater leverage. The arrangement illustrated is suitable for small tanks where there is a lack of space and, moreover, causes an immediate closing of the valve when the water reaches the proper level.

lever is swung so as to extend at a right angle Vto the valve, which latter is inserted in the aperture in the casing until the pivots c are even with the slots 2 3 in the arms a8, after which the said pivots are forced into the longitudinal plane of,

in the end of which is journaled the pivots 8o The parts are assembled as follows: The

slots until they rest in the ends thereof.

Then the valve-seat is slipped into place, and it and the supply-pipe b2 are clamped in the casing by the collar be. When the water in the tank has been drawn off, the float-lever swings upon its pivot and allows the water to force the valve back and iiow through the discharge nozzle or spout, and when the water reaches the proper level the iioat throws the float-lever around its fulorum, and the roll c2, moving in the transverse slot b3 in the valve, forces the valve up to its seat against the pressure of the water. When the valve is properly seated, the pin c2 and the pivots IOO c c are in alinement and are located in the central longitudinal plane of the valve,where by they are at a dead-center, thus locking the valve and preventing any rearward movement thereof even though the pressure of the water may be very great.

Having thus explained the nature of the invention and described a way of constructing and using the same, though Without attempting to set forth all of the forms in which it maybe made or all of the modes of its use, I declare that what l claim isl. A valve comprising a casing having a valve-seat and open-ended longitudinal slots, a valve with a transverse slot, a lever having pivot-studs lying in said slots and also having a pin or projection entering the slot in the valve, said parts being arranged whereby when the valve is seated the pin and pivotstuds are in alineinent with the valve, and a collar for preventing the lever from being displaced.

2. A valve comprising a casing having open-ended L-shaped slots, a movable valveseat, a valve-lever having pivot-studs lying in said slots, said lever being connected to said valve, and a collar pressing against said valve-seat and forcing it forward to prevent the said pivot-studs from leaving the said L- shaped slots.

3. A valve comprising a casing, with a longitudinal through-aperture and a dischargespout extending transversely thereof, a tubular valve-seat secured in the aperture in one end of the casing, a cylindrical valve sliding in the aperture in the other end of the casing, a lever removably fulorumed in slots in the casing and in line with the aperture and having means for forcing the valve against the seat, and a collar for securing the tubular valve-seat in the casing and preventing the lever from being removed.

4. A valve comprising a casing having parallel longitudinally-extended arms, a tubular removable valve-seat in said casing, a valve movable longitudinally of said arms in said casing against the pressure of Water, a lever fulcrumed in the said arms, said lever being forked or bifurcated so as to project on either side of the end of the said valve,pivotstuds for fulcrumin g said lever in said arms, said studs being substantially in a line intersecting the central longitudinal line of the valve, and means such as a pin for connecting the lever and the valve, substantially as described.

ln testimony whereof I have signed my name to this speciiication, in the presence of two subscribing witnesses, this 21st day of June, A. D. 1897.
